With the new version sdk_1.5-fb3, we have the following error in dpa_stats_create:

To investigate, we have done instrumentation on FindKeyIndex in order to display the key_value and the key_mask.
And we observe that the key_mask is alway equal to 0xFF.. instead of the value we have given in the skeleton.
Eg. we have set a mask to 0x10 and we saw that the mask is store with the value 0xFF:
